functional overexpression of gene cobK together with the other 11 of the first 12 enzymes involved in biosynthesis of cobalamin, vitamin B12, from aminolevulinic acid, in Escherichia coli strains TB1 and BL21(DE3)

cobK transposon mutagenesis for construction of a pleiotrophic mutant NS52, unable to synthesize cobalamin, and to use ethanolamine as carbon and energy source for aerobic growth, the anaerobic growth of the mutant is affected when either nitrate, nitrite, or nitrous oxide is used as terminal electron acceptor, which is reversible by addition of cobalamine or cobinamide to the minimal medium, phenotype, overview
